The isothermal and nonisothermal crystallization kinetics of nonnucleated and nucleated isotactic polypropylene ( iPP ) were investigated by DSC and a polarized light microscope with a hot stage. Dibenzylidene sorbitol ( DBS ) was used as a nucleating agent. It was found that the crystallization rat
Talc-filled polypropylene (PP) composites coupled with silane-grafted polypropylene (PP-g-Si) were prepared. Effect of PP-g-Si on the mechanical properties, crystallization, and melting behavior of PP composites was investigated. Compared with the uncoupled composites, the mechanical properties of T
The mechanical properties of polypropylene depend critically on the crystallizability of the chains, which depends in turn on their stereochemical structures. These dependences were investigated using Monte Carlo methods to generate chains having various stereochemical sequences and then scrutinizin
Early stages of crystallization of polymers may be viewed as thermoreversible physical gelation in which molecular connectivity is introduced by crystallization. Effects of shear strain on the early stages of crystallization of a commercial isotactic polypropylene are studied by dynamic mechanical e
